Walters was born in Lambeth, South London to father Raphael and mother Aisha, a former British gymnastics champion.
Having briefly played for a "Brazilian soccer school" in London until it shut down, Walters had a spell with Peckham Town at the age of seven. He went on to spend two seasons with Unique FA, before being recommended to trial with both Chelsea and Tottenham Hotspur by Unique FA founder Jamie Waller.
He was offered a deal by both, and Walters joined the academy of Tottenham Hotspur in March 2015 at the age of ten, before his family moved to Potters Bar, a town north of central London. After starting brightly in Spurs' academy, playing in older age groups as he progressed, he eventually lost interest in football, with his father saying that he felt "lost" at the time. After four years with Spurs, he played his last game with the club in March 2019, with his deal ending in June of the same year.
